gRPC 7 PERMISSION_DENIED vs 8 RESOURCE_EXHAUSTED
Both gRPC 7 (PERMISSION_DENIED) and 8 (RESOURCE_EXHAUSTED) belong to the gRPC Status Codes category. 7 indicates that the caller does not have permission to execute the specified operation. This is not for unauthenticated callers — use UNAUTHENTICATED instead. Meanwhile, 8 means that some resource has been exhausted, perhaps a per-user quota, or the entire file system is out of space.
Описание
The caller does not have permission to execute the specified operation. This is not for unauthenticated callers — use UNAUTHENTICATED instead.
Когда вы это видите
The authenticated user lacks the required role, scope, or policy to perform this action. Different from UNAUTHENTICATED (code 16), which means no credentials at all.
Как исправить
Verify the caller has the correct IAM role, API scope, or access policy. Check RBAC configuration on the server side.
Описание
Some resource has been exhausted, perhaps a per-user quota, or the entire file system is out of space.
Когда вы это видите
A rate limit was hit, a quota was exceeded, or the server ran out of memory/disk. Common with API rate limiting and resource quotas.
Как исправить
Implement exponential backoff and retry. If quota-related, request a quota increase or optimize your usage pattern to stay within limits.
